The R18 Extreme Turbo Kit from Turbo Specialties (TSI) is designed to take your 2006+ Civic DX/LX/EX coupe or sedan to a whole new level of power. This turbo kit provides more than enough power for even the most demanding customers, but is also tuned with the daily driver in mind. The installation is a completely bolt on and will work with stock engine internals. This turbo kit also features a GT25 Garrett turbo, which is extremely reliable and provides fast spool-up and great performance for the R18 engine.

The R18 Extreme Turbo Kit uses the new AEM F/IC unit for fuel management and was tuned by one of nation;s best: Shawn Church from Church Automotive. Using a stock exhaust, the R18 kit makes about 187 whp @ 6-7 PSI of boost. This translates to about 205 hp at the flywheel, compared to 140 flywheel hp for a stock R18 Civic. *With a bigger exhaust, you can expect about 200 whp, or about 220 flywheel hp, which is over a 50% increase from stock! What;s more impressive are the torque figures: 192 lb-ft of torque as early as 3000 RPM.

Key Features: * About a 50% gain in horsepower! Combined with an exhaust, you should get close to 220 flywheel horsepower on your 2006+ Civic DX/LX/EX. See the Dyno Results (with stock exhaust and cat). * Completely bolt-on installation. * Will work with stock engine internals (however, you will probably find the need to replace your clutch sooner than recommended by Honda). * Garrett GT25 turbo w/ internal wastegate set to 6-7 PSI. * Cast manifold that comes preassembled on Garrett turbo. Cast manifold replaces stock catalytic converter for optimal performance. * Features the new AEM Fuel Ignition Controller (F/IC) and high-performance Honda 410 cc/min fuel injectors w/ clips. These Honda injectors are special in that they are designed for turbo vehicles and have very good fuel atomization properties. The AEM F/IC unit comes pre-tuned to work right out of the box, but you may find that some minor tuning adjustments are necessary depending on your local conditions. * Down pipe and gasket. * Polished charge piping. * High-flow intercooler. * Stainless steel braided oil line and fittings. * Stainless steel braided water lines for turbo cooling. * Blow off valve. * High-performance air intake and filter. * Oil return hose and oil pan fitting. * All hardware, pressure lines, hoses, clamps, and couplers. * Installation instructions and wiring diagram (for customer who don;t purchase the plug and play harness). * 5 year warranty on cast parts, 1 year for accessories, and the full Garrett manufacturer;s warranty for the turbo.

Even though this kit comes pre-tuned, we recommend getting it RE-TUNED FOR YOUR SPECIFIC CONDITIONS IF YOU HAVE TROUBLE WITH THE VEHICLE STALLING. This is because the R18 Civic is fairly sensitive to elevation changes. SO PLEASE MAKE SURE YOU HAVE ACCESS TO A GOOD TUNER IN YOUR AREA THAT CAN WORK WITH THE F/IC UNIT IF NECESSARY.

Please also read the other notes that appear below. They cover some important topics and you should read all the information before purchasing this kit.

Automatic Transmission Civics: UPDATE! This kit has now officially been tested to work with the automatic transmission, but you will need to have it re-tuned slightly. This is just because the auto transmission has a different tune from the factory than a manual one.

Check Engine Light (CEL) Notes: To provide the best performance gains, the turbo manifold and piping on this kit is designed to replaces your stock catalytic converter. This will cause a CEL to be thrown by your ECU, because it detects that you removed your catalytic converter. This particular CEL causes no performance or reliability problems for the vehicle. If you really want to get rid of it, we recommend purchasing this O2 Sensor CEL Eliminator for your secondary o2 sensor. From our experience, it will stop the CEL in most all cases. It is also possible to install a universal catalytic converter underneath the vehicle without much work (you just need a muffler shop to do some minor cutting/welding and then relocate your secondary o2 sensor).

Optional Parts: We HIGHLY recommend getting the plug and play harness because it shaves about 3-4 hours off the installation time and eliminates any chance of wiring errors. If you don;t get the plug and play harness, please be CAREFUL WHEN WIRING the AEM F/IC. Just like any other electronic device, you can damage it if it is done wrong! We also suggest getting at least some sort of boost gauge so you know if your boost level is on target or not. Lastly, you may also want to purchase a turbo timer as a convenience feature. If you do not purchase one, then you should let your car idle for about 2 minutes before shutting it off after a normal driving period. Please select boomslang harness below.

Other Recommendations: As with all turbo kits, we also advise running premium fuel (91 Octane or better) and purchasing a set of 1 step colder spark plugs (Denso Iridiums perform the best).
